Why outstaff Java engineers for your mobility-as-a-service payment solution?
• Slash time-to-market by onboarding pre-vetted Spring-Boot & Microservices experts in days—not months.
• Eliminate recruitment overhead, payroll taxes and workspace costs while keeping full technical control.
• Scale squads up or down instantly to match ridership seasonality and funding cycles.
• Retain intellectual property—developers work under your processes, repositories and security policies.
• Tap into niche skills (PCI-DSS, EMV, real-time fare calculation) without long-term commitments.
• Pay only for productive hours, freeing capital for product innovation rather than HR logistics.

What technical leaders say about our mobility-as-a-service payment solution talent

“Smartbrain plugged two senior Java/Kotlin engineers with Spring Boot mastery into our fare-aggregation rewrite in five days. They crushed our backlog, integrated with our Kafka streams, and lifted test coverage from 62 % to 88 %. Performance tickets vanished and my team could focus on new APIs.”

Laura Chen

VP of Engineering

MetroWave Transit Tech

“PCI-DSS compliance scared us. Smartbrain’s vetted Java architects introduced secure tokenisation patterns, enhanced our Stripe gateway and trimmed checkout latency by 23 %. Onboarding took 4 days and the contract stayed flexible when funding shifted.”

Ethan Parker

CTO

RideShareNow Inc.

“Peak holiday demand forced us to double our JVM microservice capacity. Smartbrain delivered four experienced Java devs versed in AWS ECS and reactive streams within a week. Velocity jumped 38 % and burn-down stayed green.”

Megan Alvarez

Agile Delivery Manager

TicketFlow Solutions

“Their developers wrote clean, sonar-green code and automated 500+ Selenium tests. Result: release frequency climbed from fortnightly to weekly, bug rate fell by 41 %. Smartbrain’s contract flexibility let us keep just the specialists we needed.”

Robert King

Head of Product

AutoPass Systems

“Smartbrain’s senior Spring Cloud engineer re-architected our monolith into Dockerized services. Payment queue times dropped 57 %. He blended with our scrum rituals from day one—no cultural friction, only value.”

Olivia Brooks

Engineering Lead

UrbanMove Logistics

“When funding closed, we had to add specialists fast. Smartbrain sourced JVM/Gradle pros who understood Bluetooth ticket validators. Integration was seamless, stand-ups stayed crisp, and our internal team avoided burnout.”

Industries thriving with our Java outstaffing

Urban Transportation Platforms

Cities digitising public transit rely on Java engineers to build high-availability fare calculation, journey planning and smart-card reconciliation engines. Augmented teams integrate GTFS - real-time feeds, create OAuth-secured passenger portals, and optimise latency for peak commuter loads—all while meeting strict mobility-as-a-service payment solution security standards.

Fleet Management & Logistics

Logistics operators need real-time vehicle telemetry, distance-based billing and fuel card settlement. Outstaffed Java developers craft resilient microservices with Spring Boot, Kafka and PostgreSQL for accurate trip cost allocation, ensuring every parcel and ride is monetised within the broader mobility-as-a-service payment solution ecosystem.

Car Sharing & Rental

Shared-mobility brands employ augmented Java squads to connect mobile booking apps with backend pricing rules, dynamic discounts and payment orchestration. Our devs embed telematics APIs, engineer event-driven charging flows, and guard data in multi-tenant clusters—critical for profitable mobility-as-a-service payment solution roll-outs.

Public Transit Authorities

Government agencies upgrade legacy ticketing to contactless EMV and QR. Java consultants modernise COBOL systems, introduce Spring Integration adapters, and comply with NIST standards—saving taxpayers millions while delivering a seamless mobility-as-a-service payment solution for riders.

Micro-mobility Start-ups

e-Scooter and bike platforms face bursty traffic and micro-payments. Augmented Java experts implement reactive Vert.x gateways, ensure sub-second price calculation, and handle Stripe webhooks—keeping every short ride profitable inside the mobility-as-a-service payment solution network.

Fintech & Digital Wallets

Fintech providers cooperating with MaaS apps need tokenised card storage, AML checks and instant payouts. Our Java teams integrate PCI-compliant modules, build settlement microservices and expose secure REST APIs that power cross-vertical mobility-as-a-service payment solution payments.

Smart Parking Solutions

Parking innovators require per-minute billing, license-plate recognition and revenue sharing. Outstaffed Java developers marry ANPR streams, Spring Boot pricing engines and third-party wallet SDKs, tying parking fees back into a holistic mobility-as-a-service payment solution.

Travel & Tourism Apps

Travel aggregators stitch buses, trains and tours into bundled passes. Java augmentation delivers multi-currency payment processors, VAT handling and refund logic, enriching visitor experiences through an end-to-end mobility-as-a-service payment solution.

Automotive OEM Connected Services

Vehicle manufacturers embed subscription-based infotainment and pay-per-use features. Our Java developers craft on-board payment SDKs, OTA update pipelines and cloud gateways compliant with ISO 21434, ensuring cars integrate seamlessly into the broader mobility-as-a-service payment solution grid.

mobility-as-a-service payment solution Case Studies

Client: Metropolitan transport authority serving 4 M riders.
Challenge: Disparate bus, metro and tram systems lacked a unified mobility-as-a-service payment solution.
Solution: Our augmented Java squad refactored legacy ticketing into Spring Boot microservices, connected EMV validators via MQTT and implemented a real-time fare rules engine. Continuous delivery pipelines ensured weekly drops without service interruption.
Result: 37 % reduction in transaction latency, 22 % increase in on-time payments, and $3.4 M annual OPEX savings.

Client: Global travel app bundling flights, rail and mobility-share.
Challenge: Needed cross-border mobility-as-a-service payment solution capable of instant currency conversion.
Solution: Two Smartbrain Java experts integrated Stripe Treasury, built a reactive exchange-rate microservice and added PCI tokenisation. Automated tests covered 98 % of flows.
Result: 29 % faster checkout, 0 $ chargeback loss in first 9 months and new revenue stream from 3 % FX spread.

Client: US logistics start-up managing 12 000 vehicles.
Challenge: Legacy billing engine could not support distance-based mobility-as-a-service payment solution plans.
Solution: Augmented team of three senior Java/Spring Cloud devs containerised the monolith, implemented Kafka-driven mileage events and delivered GraphQL invoicing API.
Result: 44 % drop in billing disputes, 2-week cycle time cut to 5 days, enabling quicker revenue recognition.
